A and B because if you look on a meter stick
The perimeter of the rectangle:
The perimeter of the square:
The perimeter of the rectangle is equal to the perimeter of the square. We have the equation:
The side lengths of the square:
The side lenghts of the rectangle:
Other method.
If the first figure is a square, then the length of the sides are equal.
Therefore
Further part of the solution as above.
Answer:
4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
f = 4
No. You can only add variables that have the same exponents. Also, during addition of variables with the exponent, you do not add the exponents.
The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591
